// The following program produces striations in trivial line drawing
// as seen by comparison test in posted applet viewed in Firefox 1.5 on Win2000

int iY = 0;

void setup()
{
size(200, 200, P3D);
stroke(0, 0, 255);
}

void draw()
{
line(0, iY, width-1, iY);
iY++;
}

P3D is built for speed of drawing 3D objects, not accuracy, and therefore suffers when
drawing in drawing 2D at small sizes. there are several tradeoffs that are made and this is
why you can specify one of multiple renderers via the size() command to suit your situation.

this is essentially the same issue as bug #95.
